T/FSAS 3-2016 Room air conditioner compressor size design specifications

Scope

Scope: This standard applies to fully enclosed motor-compressors (hereinafter referred to as "compressors") used in split room air conditioners with refrigerants R410A, R22, R32, and R290, and a rated cooling capacity not exceeding 7.5 kW. Other types of compressors can refer to this standard for size design. Main technical content: 5.1 Size design specifications: The size design specifications are shown in Table 1, and the parameter code symbols are illustrated in Figures 1, 2, and 3. Table 1: Standardized design specifications Parameter number Parameter code Parameter name Explanation Whether it is a key parameter Parameter control 1H1 Exhaust pipe height The distance from the base to the exhaust pipe port Multiple parameters 2H2 Suction pipe height The distance from the base to the suction pipe port Multiple parameters 3φd1 Exhaust pipe inner diameter Multiple parameters 4φd2 Suction pipe inner diameter Multiple parameters 5φD Base mounting hole distribution diameter Multiple parameters 6Hj Rubber pad support height The rubber pad support surface 5.2.2 The rubber pad support height (Hj) and rubber pad inner diameter (φDj) shall comply with the requirements of Table 3.
